title: Effect of metabolic versus respiratory acid-base changes on isolated coronary artery and saphenous vein.
abstract: Experiments were performed on helically cut strips from coronary artery and saphenous vein to determine the relative influence of metabolic versus respiratory acid-base changes. Tensions were measured over a range of various HCO3- concentrations and pCO2's. The results suggest that tension is influenced by extracellular pH and is independent of pCO2.
